I'll make this short and not-so-sweet. My friend (And yes, it was really my friend, not ME using that as a cop out) received oral sex for the first time today. He is a seventeen-year-old boy, and he says that his penis looks thinner than it was before it happened. He wanted me to get online and find out if this is possible, and if so, is it permanate? (All this just happened today)
